    • Smith, Patrick; Barausky, Matthew I. (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)
      During commissioning of a new 8-stage CO₂ pipeline compressor, higher than expected seal vent flows were detected from the carbon ring seals in the high pressure (HP) stages. The problem was severe enough that the machine ...
    • Smith, Patrick; Sheekar, (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
      The purpose of this case study is to describe a problem with random, intermittent rotor vibration excursions in a large steam turbine These types of problems can be very difficult to diagnose, especially when the vibration ...
    • Smith, Patrick; Altimany, Gus (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries, [2019])
      Resonance in rotating machinery occurs when a natural frequency is coincident with the operating speed. The issue can be with the rotor bearing system or the pump supporting structure natural frequencies, but the resulting ...
    • Barausky, Matthew; Smith, Patrick (Texas A&M University. Turbomachinery Laboratories, 2013)
    • Smith, Patrick; Ziegler, Brent (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      Rubs in steam turbines can be especially difficult to diagnose because the vibration signature can manifest differently depending on the location, severity, rotordynamics, machine design and bear similarities to other ...
    • Smith, Patrick (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2017)
    • Smith, Patrick; Obeid, Victor; Benton, Jr., Robert; Whalen, John (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
      Centrifugal compressors and steam turbines commonly use hydrodynamic journal bearings These bearings can be fixed geometry(sleeve) or tilting pad type Most end users expect bearings to operate trouble free from major ...
    • Smith, Patrick (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
      Many compressor failures occur during transient operating conditions These failures can be prevented or minimized by having agood machinery condition monitoring program, a good machinery protection system and good maintenance ...
    • Li, Cindy; Smith, Patrick (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
      A surface condenser is a commonly used term for a watercooled shell and tube heat exchanger installed to condenseexhaust steam from a steam turbine These condensers areheat exchangers which convert steam from its gaseous ...
